DEVICE TO EMBOSS AT LEAST TWO-LAYER FLAT ARTICLES, FOR EXAMPLE, TOILET PAPER, HANDKERCHIEFS, ETC Russian patent published in 2011 - IPC B31F1/07 

FIELD: process engineering.

SUBSTANCE: proposed device comprises at least one first and at least one second pair of rolls thus making embossing roll and rubber roll. First pair embossing rolls comprises multiple uniformly distributed embossing points in amount of 20 to 70 per one cm² for flat micro embossing on at least one layer. Second pair embossing roll comprises first and second zones distributed over its area. First zone comprises multiple embossing points in amount of 45 to 70 per one cm² for flat micro embossing on at least one web of the nest layer. Second zones comprise no embossing points and make not over 40% of total embossed area and are not interconnected. Device comprises also at least one paster arranged nearby second pair embossing roll and directly behind rubber roll. Said paster applies glue on roll embossing points. Embossing rolls are arranged to provide a clearance to bring embossed layers together. To produce laminar joint of layers, connecting roll is arranged nearby first pair embossing roll.

EFFECT: set of invention allows producing high-quality flat articles with decorating pattern.
